Looks like things have been happening rapidly the last few hours.
- Jordan har closed airspace
- Lebanon has closed airspace
- Multiple flights, inclusive of QR flights have turned left over Turkey and headed for Cairo for fuel, and some have made a U turn to IST likely for the same.
- Airways (UM688) that usually are filled up on the estern side of Iraq with traffic going to/from Europe to the gulf area seems shut, no traffic going that way.

All in all, this is likely to have a lot of impact short term, with aircraft being in unexpected places, expect delays and disruptions for the next few days.
